FRANCIS H. BAGLEY, OF LOUISVILLE, IKIIBIIUGKYa WIRE application mea Agust 2e, 1922. serial No. 584,430.

To all whom, it may concern.' l

Be it known thatI, FRANCIS H. BAGLEY, a citizen of the United States, and a resident of the city of Louisville, in the county of Jefferson and State of Kentucky, have invented a new and useful Wire Terminal, of which the following is a specification.

This invention relates to wire terminals or eyelets. l V

' The rimary object of this invention is the pro uction of a device of the class specilied which will be plain in design, inexpensive to manufacture, simple to put in place, on the end of a wire, and efficient in performing the duty required of it.

Other objects and advantages will appear as the description of the particular physical embodiment selected to illustrate the invention progresses, and the novel features of the invention will be particularly pointed out in the appended clalm.

In describing the invention in detail and the particular physical embodiment selected to illustrate the invention, reference is had to the accompanying drawing, wherein I have illustrated a particular preferred physical embodiment of my invention, and wherein like characters of referenceY designate corresponding parts throughout the several views, and in which:

Figure 1 is a top 4plan view of a.termi'- nal or eyelet embodying my invention; Fig. 2 is a vertical cross sectional view on the plane indicated by the line II-II of Fig. 1; Fig. 3, is anend elevational view of the device shown by Fig. 1, viewed from the left hand end of the device, as shown in Fig. 1; Fig. 4, is the device of Fig. 1, to which has been added a wire, showing its position in top plan view, partly in section; Fig. 5, is a view of the same combination as Fig. 4 except that it is in side elevation; Fi 6 shows the completed eyeletor termina in top plan view; Fig. 7 shows the completed eyelet or terminal in side elevational view.

It is well realized by those skilled in the electrical-arts that to lace a flexible stranded wire under a bindlng nut and hold it securely is diicult and makes an unsatisfactor construction mechanically and electrica y.. This has led to the use of what are .known as wire eyelets or terminals made of an electrical conducting material, generally brass and formed to receive the end of the wire. These eyelets are defective in that. they are so constructed that they form a' shoulder, upon which as a pivot the bared wire bends back and forth until it finally breaks. It is an object of applicants invention to obviate the resence of this shoulder.

Figures, 1, 2 an 3, show applicants eyelet in top plan, cross sectional elevation and end view. It consists preferably of brass and is formed in general circular outline with a projecting wire supporting arm 1. The circular portion has a bared wire receiving channel 2, and connected inte allyl therewith is a` slightly flaring 'annu us 3, formed with a. cut-away portlon 4, for a purpose to be hereinafter described. The wire supporting arm 1, is connected tothe circular portion by athroat piece 5, and is of general U shapeas best shown in Fig. 3.

The entire eyelet is preferably constructed of a single i iece of metal of suitable shape b a punc ing or drawing operation followe by a bending operation to formthe U shaped wire sup orting arm.

In practice the endp of 'an insulatingly covered flexible stranded wire 6, formstance, is baredfor a suitable distance, the metallic strands of the core separated into about two equal portions and laid iu the circular channel 2, as shown in Figs. 4 and 5. In performing this operation the end ofl the covering of the wire is brought within the U shaped supporting arm so that it will terminate about at the beginnin lof the throat 5, as shown in Figs. 4 and 5. fter the wire issuitably positioned as described, the ends of the bared wire are twisted together tightly to hold the wire in place and the flared annulus is pressed down 'upon the wire so that it is squeezed into osition as shown in Fig. 7 The whole eye et beyond the covered wire may be then subjected to molten solder in any desired way. After soldering, if desired, the wire sup ort" armfirs wrapped ti htly about theI msulating covering and t e construction is complete, appearlng as shown in Fi .,6 and 7. e completed eyelet aor s a ready means for connecting the wire to a binding post of usual construction and the su porting arm prevents the wire from bendmg at a point where the wire is bared, whereby vthe wire might soon become weak and broken in use. f

The notched portion 4 allows the Haring annulus 3 to be pressed down tightly on' the wire without presenting a sha cut into the wire adjacent the t roat, ut

11o edgei to forms a space for the wire to rest in at this point, as shown in Fig. 7.

Although I have particularly described the construction of one physical embodiment of my invention, and explained the operation and principle thereof, nevertheless I desire to have it understood that lthe form selected is merely illustrative, but does not exhaust the possible physicall embodiments of the idea of means underlying my invention.

What I claim as new and desire to secure by Letters Patent of the United States, is:

A single-piece eyelet connector for electrical conductors, comprising a metallic body formed with a channel of general circular outline connecting with a flared annulus on its inner edge, a throat projecting from one portion thereof and a general U shaped wire supporting member connected to the throat, said annulus 'formed with a cut away portion in its edge remote from the channel, the annulus, when rolled over a conductor, forming with said channel portion a housing substantially circular in cross-section conforming to the cross-section of the conductor and said cut-away portion providing a space to receive the conductor.
